Abstract
Description
Die Erfindung betrifft eine Werkzeugmaschinenspindel mit einer mittels eines axial wirkenden Federsystems belasteten Werkzeugspannvorrichtung und einer entgegen der Spannbewegung des Federsystems einen Lösehub mechanisch erzeugende Werkzeuglösevorrichtung, wobei die Werkzeugspannvorrichtung eine in der rotierenden Spindel gelagerte, das Federsystem führende Spannstange aufweist.The invention relates to a machine tool spindle loaded with an axially acting spring system Tool clamping device and one against the clamping movement of the Federsystems a release stroke mechanically generating tool release device, wherein the tool chuck one in the rotating spindle mounted, leading the spring system Has tension rod.
Derartige, meist mit einem eigenen elektromotorischen Antrieb ausgestattete Werkzeugmaschinenspindeln sind bereits bekannt. Wird zum Lösen der Werkzeugspannvorrichtung eine mechanisch arbeitende Vorrichtung verwendet, hat die Spindel keine zentrale durch die Spindelbohrung geführte Kühlmittelzuführeinrichtung für die direkte Werkzeugkühlung.Such, usually with their own Machine tool spindles equipped with an electric motor drive are already known. Will solve the Tool clamping device a mechanically working device used, the spindle has no central through the spindle bore guided coolant supply for the direct tool cooling.
Andere Werkzeugmaschinenspindeln haben eine nur für flüssige Kühlmittel geeignete Werkzeugkühlung in Kombination mit großvolumigen pneumatischen oder bauaufwendigen hydraulischen Lösevorrichtungen. Das Kühlmittel wird bei diesen Spindeln axial durch alle in der Werkzeugmaschinenspindel integrierten Vorrichtungen gefördert.Other machine tool spindles have one just for liquid coolant suitable tool cooling in combination with large volume pneumatic or complex hydraulic release devices. The coolant with these spindles is axially through all in the machine tool spindle promoted integrated devices.
Der vorliegenden Erfindung liegt die Problemstellung zugrunde, eine Werkzeugmaschinenspindel zu entwickeln, in der über eine hohle Spannstange dem Werkzeug flüssiges oder gasförmiges Kühlmedium dauerhaft oder abwechselnd zugeführt werden kann.The present invention lies based on the problem of developing a machine tool spindle, in the over a hollow clamping rod for the tool liquid or gaseous cooling medium be fed permanently or alternately can.
Diese Problemstellung wird mit den Merkmalen des Hauptanspruches gelöst. Dazu hat die Spannstange eine Durchgangsbohrung zur direkten Kühlung des in der Werkzeugspannvorrichtung geklemmten Werkzeugs. Zwischen dem freien, werkzeugfernen Ende der rotierenden Spannstange und einem den Lösehub der Werkzeuglösevorrichtung übertragenden Stößel ist eine Kühlgas und Kühlflüssigkeit abdichtende Gleitringdichtung angeordnet.This problem is solved with the Features of the main claim solved. To do this has the tie rod a through hole for direct cooling of the in the tool clamping device clamped tool. Between the free end of the rotating tension rod and a transferring the release stroke of the tool release device Pestle is a cooling gas and coolant sealing mechanical seal arranged.
Weitere Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung einer schematisch dargestellten Ausführungsform.Further details of the invention result from the subclaims and the following description of a schematically illustrated embodiment.
